I'm working with a support engineer now to figure this out, but I want to ask you guys also.
Filer: FAS2240 running 8.1.1 7-Mode
Windows OS: Windows 2008 R2
I'm running this on my Exchange 2010 server for the TLOGs volume mount point.
PS C:\Windows\system32> Get-NaHostDisk
HostDrivePath Disk Size ControllerPath
------------- ---- ---- --------------
C:\ 0 100.0 GB
1 100.0 GB
C:\Exchange2010\Databases\ 2 1.0 TB WST-NETAPP01:/vol/exch2010_mbox01_db/qtree01/mbox01_db01
C:\Exchange2010\TLOGs\ 3 1004.0 GB WST-NETAPP01:/vol/exch2010_mbox01_tlog/qtree01/mbox01_tlog01
C:\Exchange2010\PublicFolders\ 4 99.6 GB WST-NETAPP01:/vol/exch2010_mbox01_pubfolders/mbox01_pubfolders
I ran the following command:
Measure-Command { Invoke-NAHostVolumeSpaceReclaim -Path C:\Exchange2010\TLOGs\ -confirm:$false -Unmapsize 2MB } | select TotalMinutes,TotalSeconds
The first time took 37 minutes and, according to Windows, I went from having 25GB free to 828GB free.
However, nothing changed on the filer ... I still only have 23GB free.
Filesystem total used avail capacity Mounted on
/vol/exch2010_mbox01_tlog/ 1069GB 1045GB 23GB 98% /vol/exch2010_mbox01_tlog/
Is this normal behavior? Am I supposed to see the free space on the LUN like I do in Windows?
How does this affect snapshots? According to Best Practices, SME puts all of my backups in the TLOG volume so I really need to make sure there's always room available there.
